1.1 Overview

The chartplotter is a sophisticated electronic charting system, which uses GPS,
dGPS or Loran-C technology to make navigation as simple and accurate as
possible.

Introduction

The chartplotter displays chart information from the C-MAP NT
electronic chart cards (C-Cards), and position information from satellites or
land-based radio beacons. It can also display virtually any data available from
other compatible instruments in your system.

The chartplotter is designed to be extremely easy to use, while providing
powerful options for handling data and customizing the system to match your
requirements. Everyday functions are available at the touch of a button, with as
much or as little help as you need. The on-screen prompt and menu system,
from which you can select the functions and options you require, simplifies
even complex tasks such as editing stored route data.

The monochrome display unit can be installed either above or below deck; the
color display must be mounted below. The display can be illuminated for night­time use.

Features

• Chart display with zoom and pan control; a background world map is

included, and there are two slots for inserting C-MAP NT C-Cards for large­scale cartography.

• Vessel’s position displayed, with optional heading, course, tide and wind

vectors, and optional track history display.

• Display options to control cartographic data displayed and windows for

displaying navigational data, including Course Deviation Indicator (CDI)
and Bearing Deviation Indicator (BDI), from other instruments.

• Plotter mode which allows the use of the chartplotter at ranges for which no

chart information is available.

• 8 languages.

Introduction

Functions

• Quick and easy on-screen route setup and control.

• GOTO function navigating immediately to a waypoint.

• Event and mark recording.

• Edit and review functions for stored route, waypoint and event data.

• Setup options to customize the chartplotter according to your own system

preferences, such as chart orientation (north up, course up or head up),
display windows, and alarm setup.

• Ruler function for measuring chart distances.

• Centre options for centering the chart on the ship, cursor, or a specified

position, and a Home Mode for displaying the vessels current position and
tracking information.

• Alarm reporting and control, and a range of timers including countdown and

elapsed timers.

• Log record.

• Print option.

Navigational Displays

The chartplotter is compatible with the SeaTalk® and NMEA 0183 standards.
Full functionality of the chartplotter is achieved when it is part of an integrated
system, with other equipment connected via Seatalk or NMEA 0183. Data from
this equipment including position, waypoints and routes, is displayed on the
chartplotter and is used in calculations. Details on connecting other equipment
are given in Chapter Seven.

Chapter 1: Introduction 3

1.2 The Chart Display

The chartplotter includes a small-scale world map that can be used for route
planning. Detailed navigation information is displayed when a chart card is
installed.

Once the position fix has been established, the screen shows the chart area and
associated data that were displayed when the chartplotter was last used.

The chartplotter screen includes a cursor data box which normally provides the
following information:

• The cursor position, in either latitude and longitude or TDs, depending on

your setup

• The vessel’s Course Over Ground (COG) and Speed Over Ground (SOG)

• A mileage scale ruler in nautical miles

• The units in which depth data is displayed

• The cursor’s bearing (BRG) and range (RNG) from your vessel’s current

position

The

Chart Display

The cursor data box is also used to display the vessel’s position and the range
and bearing to the active waypoint, when the chartplotter is in Home Mode (see
Section 3.2).

An example chartplotter chart display, in its default configuration with a chart
card installed, is shown in the top illustration overleaf.

The chart display can show additional information, depending on the current
data and on your setup selections, as shown in the example chartplotter display
in the bottom illustration opposite. You can also display the cursor position
from other compatible displays (see Chapter 6).

Note: If required, you can use the setup options to change the units in which
information is displayed, turn off the cursor data box and soft key labels, and
change the chart orientation (see Chapter 6).

1.3 Operating Controls

You operate the chartplotter in a variety of ways; the control keys on the display
unit are used with on-screen facilities such as pop-up menus. These include:

• A trackpad providing up, down, left, right and diagonal control of an on-

screen cursor.

• Eight dedicated (labelled) keys.

• Four soft keys with labels displayed on the screen.

• Pop-up menus, displayed on-screen, from which you select options.

• Database lists, displayed on-screen, which enable you to edit items.

move diagonally. The cursor moves faster as you continue to press the
trackpad. The current cursor position is shown in the cursor data box.

The cursor is displayed as a cross symbol (✣) on the chart. It is used to:

• Select a position on the chart.

• Select an item e.g. waypoint, on the chart.

• Pan the chart display.

➤ Try using the trackpad now to move the cursor around the chart. You can use

short presses on the trackpad to move the cursor small distances, or press and
hold to move the cursor quickly.

As you move the cursor to the edge of the display, the display pans across the
chart so that the area you have moved to remains in view. If you continue to
scroll, the chart is redrawn on the screen at intervals.

If you move the cursor over an object for which there is information available,
an Object Data Box appears at the top of the screen (see Chapter 2).

Dedicated Keys

These keys have fixed functions. Some keys can be used in two ways:

• Press: Press the key momentarily and then release it. This method is used for

most key operations.

• Press and hold: Press the key and hold it down for the length of time stated

(for example, 3 seconds), and then release it.

When you press a dedicated key, one of the following happens:
a) The associated operation is actioned, e.g. change chart scale (RANGE).
b) A pop-up menu is displayed, providing further options.
c) A set of soft keys is displayed, providing further functions.

As you press a key, a single audio beep confirms the key action. If the key-press
is not valid for the current screen or mode, three rapid beeps sound to indicate
that no response is available. If required, you can turn the key beeps off as part
of your set up procedure (see Chapter 6).

The dedicated keys are defined in the illustration on page 9.

155_C1_1.p65 10/12/98, 11:316

Chapter 1: Introduction 7

The Soft Keys

The four keys below the screen are called soft keys because their functions
change according to the operation. The soft keys are grouped into related sets
and subsets providing access to the various functions. The soft key labels are
displayed on the screen just above the keys. The default soft keys are displayed
until you press a key, or select an item on the screen; the soft keys associated
with the action are then displayed.

You can control whether or not the soft key labels are displayed all the time,
using the system set up as described in Chapter 6. If no labels are displayed,
press one of the soft keys to make them appear. The labels disappear again if
you do not press a key for 7 seconds.

Similarly to the dedicated keys, when you press a soft key one of the following
happens:

a) The associated operation is actioned, e.g. GOTO.
b) A sub-set of soft keys is displayed, providing further functions.
c) A pop-up menu is displayed, providing further options.
d) The appropriate database list (route, waypoint or track) is displayed.

As with dedicated keys, when you press a key, a single audio beep confirms the
key action. If the key-press is not valid for the current screen or mode, three
rapid beeps sound to indicate that no response is available. If required, you can
turn the key beeps off as part of your set up procedure (see Chapter 6).

Soft Key Default Functions

In default mode, the soft keys provide a quick method of performing the tasks
you will probably use most often, and which are described in detail in Chapter

3.

D3352-2

You use the soft keys to access the following functions:
ROUTE Set up or edit an on-screen route of waypoints, and navigate

towards them in turn

left indicate the signal strength for each of the currently located satellites.
Initially, the chartplotter uses the predicted satellite positions, and the
bargraphs are blank until the satellites are located.

The GPS searches for the strongest signals: at least four are required for an
accurate position fix. If the signals from the currently located satellites are
not strong enough, the GPS searches for other satellites and these are
displayed in turn.

3. To clear the Fix Status window and display the chart, press the CHART soft

key. (You can redisplay the Fix Status window later if required, as
described in Chapter 6.)

If a position fix has not been established, a “Fix Alarm” message is
displayed. You can clear the alarm by pressing any key. The unit will beep
every few seconds to indicate there is no position fix, until the position has
been established.

The soft keys INITIALIZE and BEACON can be used to initialize the GPS and
to manually set up a differential beacon. These functions are described in
Chapter 6.

2.4 Using Chart Cards

The chartplotter has a built-in world map that can be used for route planning.
Most areas are covered on a scale of about 500nm per inch on the screen
(200nm per cm), although some populated areas have details down to 300nm
per inch on the screen. The chartplotter displays a scale indicator on the screen
for all chart displays.

To use the chatplotter as a navigation aid, charts with detailed information for
the area you wish to navigate are required. These are available on C-MAP NT
electronic chart cards (C-Cards), each of which can store as many as 20 charts
in an electronic format. A single C-MAP chart normally provides as much
information as is available in paper charts for that geographic area, with detail
up to 0.05nm per inch.

The chartplotter allows you to install two chart cards at the same time. You can
also use the slots for C-MAP Memory C-Cards, which allow you to store and
retrieve data such as waypoints and routes.

Note: You can insert and remove cards while a chart is displayed. The chart
information is retained until the chartplotter redraws the screen: for example,
when you pan outside the current area, or use the RANGE key to change the
chart scale.

Inserting a Chart Card

➤ To insert a chart card:

1. Check that the card is the correct format (C-MAP NT C-Card), with the

required chart stored on it.

2. Open the card cover, at the top left of the chartplotter front panel, by

pushing the latch to the left and then opening the cover as shown in the
illustration on the following page.

3. Hold the card with the printed text pointing towards the right and the

correct way up, as shown in the illustration.

4. Gently push the card into one of the two sockets. It will only go in if it is the

right way round.

155_C2_1.p65 10/12/98, 11:3114

Push the card in as far as it will go, then move it to the left so that the top is
under the retaining pegs. Release the card so that it is held in place by the
pegs.

5. Close the card cover so that is clicks shut, to stop water splashing into the

chartplotter.

2.5 Controlling the Chart

You control the chart display using the cursor and control keys. You start all
operations with the default soft keys displayed (this is referred to as the default
screen in the following sections).

Controlling the

Chart

When you have completed an action using the soft keys sub-sets, to return to the
default screen, press CLEAR; you may need to press CLEAR several times to
back-track through the sub-set hierarchy.

Note: If you have set up your system so that the default soft keys are not
displayed all the time, press any soft key to display the labels.

Although you can use your chartplotter with the whole screen devoted to the
chart, you can also display navigation data in one or two windows, with the
chart displayed in the rest of the screen. Navigation data windows are controlled
using the DISPLAY key.

This section describes how to:

• Move around the chart by panning the display, changing the chart scale and

changing the chart centre.

• Display navigation data.

Note: The orientation of your chart (North Up, Course Up or Head Up)
depends on your choice when you set up the chartplotter, as described in
Chapter 6.

The chart controls are summarised in the illustration on the page 9.

the Chart

Controlling

Moving the Chart

You will normally operate the chartplotter with the chart showing your vessel’s
current location. In the default North-Up orientation, the display is in True
Motion mode, in which the vessel moves across the screen. You will need to
move the chart if your vessel moves out of the area currently displayed, or if
you wish to examine or place marks/waypoints in another area.

There are three ways in which you can move the chart:

• Use the trackpad to move the cursor to the edge of the chart. The chart will

pan across (see Section 1.3). This method is useful if the area you wish to see
is only just off the screen.

• Use the RANGE key to zoom out to a small scale chart, move the cursor to

the centre of the required area, then zoom in on the new area . This method is
useful if the area you wish to see is a long way away.

• Use the CENTER soft key to center the chart on one of a choice of positions:

the vessel’s position, the cursor position or a specified position .

• Automatically re-center the chart using the HOME option.

21Chapter 2: Getting Started and Controlling the Chart Display

Note: If you have selected a chart display with one or two data windows, the
chartplotter will treat the start of the data window as the edge of the chart.

Changing the Chart Scale

The RANGE key allows you to change the cartography scale so that you can
see a smaller or larger area on the screen. Plotter mode is available to allow you
to zoom into a smaller area, even when no chart data is available for that scale.
Chapter 6 describes how to set plotter mode on/off.

Contrllong

The Chart

You can change the chart scale for two purposes:

• To see either more detail (a smaller area) or a larger area on the screen

• To move the display to another area of the chart, by zooming out to a small

scale chart, then zooming in on another area

Small scale charts give you the wider view, but without the level of detail that
you may need in order to navigate safely. The amount of detail that is visible
depends on the amount available for that chart, and also on how you have
specified the cartographic detail when you set up your chartplotter (see Chapter

6).

➤ To zoom in to a larger scale chart:

1. Use the trackpad to position the cursor in the area you wish to see in more

detail.

2. Press the lower part of the RANGE key.

The section of the chart around the cursor is enlarged to fill the screen with
a larger-scale chart showing more detail. The cursor is now positioned in
the center of the screen.

The range scale indicated at the top left of the screen is updated.
Note: If you hold down the RANGE key, the range scale display is updated

quickly without the chart being redrawn. Simply release the key when the
required scale is shown, and the chart will then be updated.

3. If further chart enlargement is available using the current chart card you can

press the bottom of the RANGE key to zoom in again, repositioning the
cursor first if required.

An area of further chart detail is indicated by a box around the area.

4. When no further chart detail is available, as you press the bottom of the

RANGE key, the effect depends on whether you have set Plotter Mode on
or off as follows:

- If Plotter Mode is off (the default setting), the chartplotter beeps three times

and the range scale remains unchanged.

- If Plotter Mode is on, the range scale is increased and the display shows

grid lines and no cartography. The letter “P” is displayed after the scale rule

The cartographic information is restored when you return to a chart scale

for which the information is available.

➤ To zoom out to a smaller scale chart, simply press the upper part of the

RANGE key as many times as required. If no smaller scale chart is available,
then the chartplotter beeps three times when you press the upper part of the
RANGE key.

Changing the Chart Center

You can move a chosen point to the center of the chart, using the CENTER soft
key. The chosen point can be the vessel’s position, the cursor position or a
specified position.

You can also select Home Mode, which centers the vessel, homes the cursor
and changes the cursor data box to provide information about your vessel’s
position.

Note: Changing the range scale always centers the chart on the cursor.

Centering the Chart

➤ To center the chart using the CENTER options:

1. From the default soft key display, press the CENTER soft key.

The following soft keys are displayed:

2. Press the soft key for the center option you require (or CLEAR to return to

the default screen without change):

- CENTER SHIP moves the chart so that your vessel’s position is at the

centre of the chart, and repositions the cursor so that it is over the vessel

Using Home Mode

When you select the HOME option, the chartplotter centres the vessel and
changes to Home Mode. In this mode:

• The cursor is not displayed, and is fixed to the vessel’s position

• The cursor data box displays the vessel’s current position; if you are tracking

to a waypoint, it also displays the waypoint name, bearing and range

• In Head Up or Course Up modes (see Chapter 6), the display changes to

Relative Motion, in which the chart moves to keep the vessel in the centre of
the display.

➤ To return to the standard cursor and motion mode, press the trackpad. The

cursor re-appears and the cursor data box displays the cursor position data.
